Xray科學上網簡要

在中國大陸,科學上網的需求對於技術人員,或者特定人羣,始終是存在的。從最開始的 vpn 到 shadowsocks,再到 v2ray,最新的爲 xray,包括其它的,目的都是爲了自由訪問互聯網,獲取必要資訊。 本文介紹在 linux pc 環境下,命令行模式科學上網配置, 非 GUI 外部依賴少,不需要等其它軟件更新,即可獲得最新功能,mac 應該也可以類似操作,但 mac 軟件生態較好,一般下載對應的 app 安裝即可,不要手動配置。

1. 購買海外主機

建議日本/新加坡/美西,或者香港主機,看雲服務商,自己測試下速度,選速度快晚高峯不卡頓的

2. 服務端配置

  • xray github 倉庫下載最新的平臺軟件包
  • 解壓軟件包到自定義目錄, 我選擇的目錄爲/opt/xray, 如下所示,config.json 爲稍後創建的配置文件,其它 4 個爲壓縮包默認提供,無需更改
 1root@tokyo:~# ls -al /opt/xray/

10-rwxr-xr-x 1 root root 20606976 Jan  1 08:00 xray
  • 使用 vim 或者 vscode 等編輯器配置 config.json 文件
 1root@tokyo:~# cat /opt/xray/config.json

24            {

34            "http/1.1"
35            ],
36            "certificates": [
37            {
38                "certificateFile": "/root/.acme.sh/mephisto.cc/fullchain.cer",   # 改成你的證書
39                "keyFile": "/root/.acme.sh/mephisto.cc/mephisto.cc.key"  # 改成你的key
40            }
41            ]
42        }
43        }
44    }
45    ],
46    "outbounds": [
47    {
48        "protocol": "freedom"
49    }
50    ]
51}

mephisto.cc 是我購買的域名,證書部分由 caddy2 自動搞定,找到證書地址填到上面對應行即可, 無域名的配置方式,請參考 xray 的相關文檔

  • systemd 配置,不會操作的搜索學習下,結果如下

    • 進程監聽狀態確認, xray 的 444 端口已經開啓監聽,這個端口是上面配置的

      1    root@tokyo:~# ss -lntp |grep xray
      2    LISTEN 0      4096               *:444             *:*    users:(("xray",pid=2403220,fd=3))
      

    至此,服務端相關配置完成

3. 客戶端配置,linux 命令行客戶端配置, 和服務端相差不大,只是配置文件 config.json 內容不同

routing 和 dns 部分看起來複雜,請查看 xray 的文檔,普通用戶都不需要怎麼改動,翻牆夠用了

有人可能要問了,接下來怎麼使用呢,操作很簡單,我平時用兩個瀏覽器,chrome 主力,firefox 配置上面的上述兩種代理即可 setting/General/Network Settings/Settings/Manual proxy configration 下圖所示

firefox proxy

另外,Gnome 等桌面也有全局網絡代理設置,chrome 和 firefox 有相關代理插件可用,終端裏面也可以配置環境變量的方式使用,不一一列舉。

最後,特別說明手機端 ios 去美區下載 Shadowrocket 也可以配置使用
